Fermatean neutrosophic rough set
In order to balance uncertainty, a reasonable approximation of a crisp set that yields lower as well as upper approximations of the set is Graduate made.Here, first, a special class of Fermatean Neutrosophic Set is devised by associating the Neutrosophic Set with the Fermatean Fuzzy Set.A relatively new concept of Fermatean Neutrosophic Approximati
